Polyurethane waterproof coating makes the bathroom waterproof, how to paste tiles

1.Clean the surface of the base layer, the base can be wet, but there can be no open water;

2.During the construction of the wet paving method, the dry base layer needs to be sprinkled with water to moisten; During the construction of the dry paving method, the base treatment agent can be directly applied on the dry base layer and then paved.

Construction precautions When mixing polymer cement slurry, pay attention to the water-cement ratio so as not to affect the bonding quality of the waterproof layer.

Before the lap part of the coil is bonded, it should be avoided that there is cement mortar to pollute the lap surface.

It is not allowed to step on or scratch the constructed waterproof layer within 48 hours after the completion of the membrane paving. Polyurethane waterproof coating is an oil-based waterproof coating with insufficient adhesion and is prone to hollowing, resulting in brick falling on the wall.

Hello, about your question I think 1, after the wall is made of waterproof coating, we must not be able to directly paste the wall tiles on it, we need to make a protective layer of mortar waterproofing agent on the wall, and we can paste the tiles after the mortar protective layer is completely dry, and the quality of the tiles will be better and better, so that the water absorption rate of the tiles will be reduced, and it is difficult to meet our needs by using the sand cement pasted tiles used to pave.

2. And for the current waterproof coating base is mainly based on the concrete wall, we only need to do a good job of waterproofing before we can paste the tile, but now the market also has a waterproof coating that can be done directly on the tile, but in fact, this method is still unreliable, and there is basically no waterproof effect after the best.

3. Can you directly paste tiles directly on the waterproof coating, but also depends on our construction quality and material quality, at present, there are cement mortar waterproof coatings on the market, so that the waterproofing can penetrate into the wall well, forming a better waterproof layer, and the adhesion between the surface and the tile is also very good, and it can also prevent mildew.

Try it with cable tile glue?

The oily polyurethane waterproof coating is pasted with wall tiles and hollow drums, and the base layer is not well treated. When the polyurethane waterproof coating is used for bathroom waterproofing, it is necessary to shake the sand on the top, and use cement slurry mixed with construction glue before pasting the tiles to ensure that the tiles have enough adhesion to the base layer so that they will not be hollow.
